To find out how I come up with the cost p per tonne (OPEX) if a feasibility study isn’t availe, I refer you to the note at the bottom of this page.

Cut-off grade estimation - QueensMineDesignWiki

Calculating The Cut-Off GradeMineral ClassificationAdjusting The Cut-Off GradeReferencesThe most simplistic way to determine cut-off grade is through the break-even and internal method. This method is easy to use and involves minimal background information. It is preferred as a first estimate, and is most effective in the early planning phases of a project. Although the limited number of parameters makes this method a good first step, it is not ideal to use this method in the long term, since it does not take production capacity or discount rates into consideration.The internal
